Description
Intended Uses: The kit is a competitive inhibition enzyme immunoassay technique for the in vitro quantitative measurement of docosahexaenoic acid in serum, plasma and other biological fluids.
Principle of the Assay: This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to docosahexaenoic acid has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled docosahexaenoic acid analogues and unlabeled antigen (Standards or samples) with the pre-coated antibody. After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of docosahexaenoic acid in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of docosahexaenoic acid in the sample
